For me,
Tracy's sparse, Zen-like restorations compel one to look at the dinosaur
figure in toto, with multiple points of focus, as each drawing he
presents is the result of long hours of careful thought and comparisons.

I've
to add to this that "How To Draw Dinosaurs" is a MUST HAVE for all people who
wanna begin in paleoart. I bought both, I'm learning MANY LITTLE DETAILS I
didn't see before.
